GC Athletics

We believe that a truly comprehensive education challenges the whole person. We are proud of our superior athletic program, which is distinguished by both its breadth and the performance of our individual students.

Teams and Schedules

Concessions Volunteer Sign-Up!

Sign up your club/team/organization up to volunteer for concessions help to earn a share of the profits!

We have streamlined the process and now all sign-ups are online through Signup Genius. This free service will allow either individuals to sign up with a valid email address, or for parent and volunteer coordinators to sign up to cover multiple spots at once. The signups are currently live for all home games and after-school sessions through October.

*All volunteer slots are "first come, first served."
